If this is a real bug, then it needs a fixes tag. The fixes tag helps
us know whether to back port or not and it also helps in reviewing the
patch. Also get_maintainer.pl will CC the person who introduced the
bug so they can review it. They are normally the best person to review
their own code.
Here it would be:
Fixes: c5a8a8498eed ("ipvs: Fix uninit-value in do_ip_vs_set_ctl()")
Which is strange... Also it suggest that the correct value is -EINVAL
and not 0.
The thing about uninitialized variable bugs is that Smatch and Clang
both warn about them so they tend to get reported pretty quick.
Apparently neither Nathan nor I sent forwarded this static checker
warning. :/
